AMALGAMATING-POCKET.

Application tiled July 6, 1915.

To all whom z't may concern:

Be it known that I, ERAs'rUs B. BENNETT, a citizen of the United States,and a resident of the city and county of Denver. State of Colorado, haveinvented certain new and useful Improvements in Amalgamating- Pockets;and I do declare the following to be a full, clear, and exactdescription of my invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in means for treating ore by theamalgamating process, and the invention has for its object the provisionof pockets adapted to contain a quantity of mercury and through whichpockets the ore passes.

Another object of the invention is to provide means for causing the oreto be uniformly and constantly fed through the pockets over the mercury.

Another object of the invention is to provide means for dissipating theore to cause the latter to be thoroughly exposed to the mercurycontained within the pockets.

Another object of the invention is to provide means for preventingcongestion of the ore in the pockets.

With these and other objects in view, which will become apparent in thefollowing detail description, I will proceed to describe my inventionwith reference to the accompanying drawing.

In this drawing, Figure 1 is a longitudinal sectional view of a tank inwhich the pockets are arranged, the view showing the riiiies, which formthe pockets, in cross section; Fig. 2 is a plan view of the tank; Fig. 3is a cross sectional view of one of the riiles forming the pockets, thesaid view being taken on the line 3 3, Fig. 2; and Fig. 4 is atransverse view, partially in section and partially broken away, showingone of the water feed pipes disposed in the pocket, the said view beingtaken on the line 4.-4 looking in the direction of the arrow.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Let the numeral 5 designate a tank, having an inclined bottom 6, onwhich the improved amalgam pockets are disposed. These pockets, whichare designated by 7, are formed by curving the lower extremitiesSpecification of Letters Patent.

of the bottom of the boxes. I employ a plurality of these boxes 8,successively arranged so that the ore will pass through each of them.The rear extremity of each of the boxes 8 is turned upwardly at anangle, as shown at 9, and is overlapped by the curved part 10, of theadjacent box, as shown at 12, the said curved part 10 of each box beingshaped to form a recess for the reception of the upwardly turned partsof the adjacent boxes. These boxes S are provided with sides 13, whichextend above the top of the pockets 7, whereby the ore is prevented fromover-flowing the pockets 7 at the extremities of the latter. These boxes8 are secured to the inclined bottom of the tank 5 by means of fasteningdevices 14, the said boxes also occupying positions inclined to thehorizontal and corresponding with the inclined bottom 6 of the tank 5.The pockets 7 extend transversely of the tank 5, and a transverse waterfeed pipe 15 is disposed in each of said pockets longitudinally of thelatter, a space being left between said pipes and the bottom of thepockets, through which the ore is adapted to pass over the mercury.These water feed pipes are provided with relatively narrow longitudinalslots 16 disposed to discharge a sheet of water forwardly in thepockets. Thus, this sheet of water will feed the ore forwardly throughthe pockets and at the same time dissipate the ore to cause same to bethoroughly exposed to the mercury, in which the values are retained,while the waste material passes out of the pockets. It will also beunderstood that this sheet of water will prevent the ore from congestingin the pockets 7 for the reason that the space between the pipes l5 andthe mercury in the pockets will always be kept open by the iowing water,the latter influencing the passagel of the ore through said space.

An ore feeding cylinder 17 is journaledV at the forward extremity of thetank 5 and l feeds the ore to the first box 8, as indicated by thearrow, and thence the ore travels successively through the boxes 8 andis finally discharged from the tank 5 through a transverse slot 18,disposed in the rear end of the tank adjacent the bottom of the latter.It is understood that the tank 5 is adapted to contain a quantity ofwater in which the cylinder 17 is partially submerged and the boxes 8entirely submerged.

The water feed pipes 15 are supported by the opposite sides of the tank5, through which the said pipes pass. A feed, or supply main 19 connectsthe pipes l5, whereby water is constantly supplied to the latter.

It will be understood that my improved pockets may be employed withoutthe tank 5, and also that it is not necessary to have the pipes entirelysubmerged in water, as is the case when the tank 5 is filled with water.

While I have described and illustrated herein a specific form of myinvention, it is understood that I am not limited thereto and that thesame may be modified and varied without departing from the spirit of theinvention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is. n

`1. A machine for treating ore, comprising a tank having an inclinedbottom, a box arranged on the inclined bottom of said tank, said boxhaving its forward extremity upwardly curved in the shape of a segmentof a circle, a water supply pipe disposed above said box and having alongitudinal feed slot tangential to the pipe bore, said box adapted tocontain a quantity of mercury, a space being left between said watersupply pipe and the normal surface of the mercury in said box, and theslot of Said water supply pipe being directed to the center of thenormal surface of the mercury.

contain mercury, and a pipe disposed transversely in said tank abovesaid pocket and having a slot therein tangential to the bore of the saidpipe `and directed forwardly.

el. A machine for treating ore, comprising a tank having an inclinedbottom, a pocket disposed on said inclined bottom in an inclinedposition, said pocket adapted to contain mercury, a pipe arranged insaid tan-k normally above the surface of the mercury in said pocket, andsaid pipe having a slot therein tangential to the bore of said pipe anddisposed to discharge water int-o said pocket in a forward direction.

In testimony whereof, I afx my signature in the presence of twowitnesses.
